Weight Paint Box is a rigging utility that introduces a deformation box workflow for weight painting, replacing the traditional brush. It allows users to manipulate weights by interacting with the faces of a bounding box, applying smooth operations with independent control over strength and direction. The tool supports handling multiple vertex groups simultaneously, mirroring operations, and using the box as a masking volume to hide geometry during the painting process.

The add-on also includes a Draw Bone tool for generating custom armatures. It features tools for placing chains like arms, legs, fingers, spines, and tails directly in the center or on the surface of character meshes. It integrates with Rigify, offering pre-configured modes for basic human and MetaHuman rigs, alongside automated chain generation, alignment, and symmetry controls.
